The Givi Sport-T Tanklock Bag is a hard topped sports tank bag with a 4 litre capacity made in EVA, thermoformed and covered with Guzy600D and PU UV resistant materials, in accordance with ISO 4892-2:3013 regulations including 500 hours exposure in a Q-Sun Xenon test chamber. This features side reflective inserts, carry handles, inner case for sunglasses, adjustable shoulder strap for transportation, transparent window to store and use a smart phone, high-visibility rain cover to increase visibility, zip pulls designed to be used with a safety lock and this is prepared for a cable port, to be combined with the POWER HUB accessories for electronic devices.The TankLock system on the GIVI XS307 TankLock Tank Bag eliminates the need of straps or magnetic limpets, previously used to fasten your tank bag to the bike. Thanks to a small mounting ring attached to the tank cap, the bag can now be attached by simply aligning it to the mounting ring and pressing lightly until you hear the classic click. Equally easy is the removal of the bag; to release it you can just pull the red lever located at the base of your tank bag. The mounting rings depend on the make and model of your motorcycle, and you need to check the compatibility list to establish which ring is for use with your model of motorcycle. Please Note: This tank bag uses the Tanklock fitting system to lock and unlock it from your motorcycles fuel tank. It requires an additional mounting kit.
